IMPROVEMENT IN MAGAZINES FQR HEATlNG-STOVES.

Specification forming part of Letters Patent No. 127,865, dated June 11, 1872.

To all whom it may concern:

Be it known that I, WILLIAM A. GREENE,

of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Heaters, of which the following is a specification: This invention consists in making the magazine with a small circular mouth and radial dischargin g-spaces, so as to protect it at the mouth from the intense heat to which magazines, as ordinarily constructed, are subjected.

Figure 1 is a sectional elevation of a heater or hot-air furnace, showing my improved magazine taken on the line as w of Fig. 2. Fig. 2 is a horizontal section taken on the line y y of Fig. 1.

A is the ash-pit; B, the fire-pot; G, the combustion-chamber; D, the base-heating chamber E, the pipes leading from the combustionchamber to the chamber D; E ,the escape-pipes for the smoke. F is the magazine, and G the outer case. The combustion-chamber O is arranged above the fire'pot concentric with the base, and the exterior case G and the fire-pot B and magazine eccentric thereto, the same being nearer the front of the stove than the back, as clearly indicated, for the purpose of providing greater space between the magazine and the outer wall of the chamber 0.

The mouth of the magazine, which is the feature of the invention, is contracted considerably more than the openings of the ordinary magazines thereat-say, to about one-half of the sizeand providing the narrow radial extensions N in connection therewith, the radius of which is slightly greater than that of the cylinder above. The main object of this arrangement is to so shape the mouth that the volume of coal passing into the fire-pot will not be so great in any part as to support combustion of the coal as high as the said mouth, thereby preventing the intensity of heat thereat common to the wide-mouthed magazines now used and so destructive tothem. The reasons for the combustion of coal not being so high as the month of the fire-pot is that.

the reservoir forms a column of coal so much smaller ornarrower than the same that the coal cannot spread out or enlarge until it reaches the middle or thereabout of the fire-pot. Another object is to so extend the .discharge of coal across the fire-pot as to increase the area of surface subject to combustion, and to afford greater space above the coal in the pot for the combustion of gases, which space is formed between'the walls of the said radial spaces and the contracted circular part 0.

The course of the products of combustion is thus from the fire-pot B into'the combustionchamber 0, whence they may escape directly into the flue E, or they pass around the front ends I of the passages H along the channels K to the fines E, thence down to the chamber D, and up through the pipe E.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is-

The magazine having a small circular mouth, 0, and the radial discharging-spaces N, substantially as specified.

The above specification of my invention signed by me this 26th day of January, 1871.
